What's included in the kit?

  • x1 Dual Ball Mounting Base
  • x1 standard 7cm Carbon Fiber + Kevlar hybrid mounting arm
  • x1 device holder (choose between our Universal, XL Universal or DiabloM6 Magnetic Phone Mount)

Note: For kits containing 2 device holders (2 phone holders, phone holder + tablet holder), 2 Carbon Fiber + Kevlar Mounting Arms are included.

Base-Only Option

You may opt for just the Dual Ball Base and customize from there (no mounting arms or device holders are included with the base only option).

Our base comes with 2 integrated 20mm mounting balls that work with any of our device holders and mounting arms.

There is also a 3rd mounting location concealed within the Bulletpoint logo that is AMPS compatible which means you can mount up to 3 devices in total.

We sell AMPS Mounting Balls separately but you may also choose to secure a 3rd party AMPS-compatible mount as well.

In addition, the Platform Base features an integrated camera-ready 1/4"-20 threaded insert so you can mount your camera using a 1/4"-20 adaptor (not included).

    A rock solid mounting system starts with a rigid mounting base.

    Our Metal Series bases are made from precision laser cut metal which results in a solid foundation for mounting your devices.

    Patent Pending

    All hardware is included for a straightforward installation that is extremely sturdy.

    2 possible installation options are available and depend on your vehicle's dash.

    1. Rubber Well Nuts (Heavy Duty - no panel removal necessary)
    2. Nuts & Bolts (Heavy Duty - panel removal required)

    Note: Requires removal and drilling the dash panel (4 holes). Includes all necessary hardware for an easy installation.

    Buy with confidence knowing that you're backed by our Limited Lifetime Warranty.

    Our DiabloM6 magnetic phone mount requires a thin metal plate affixed to the back of your phone. Please note that this also prevents Wireless Charging. The DiabloM6 is not directly compatible with MagSafe equipped iPhones. 

    The metal plate may not stick to all phone cases. For example, many silicone cases have non-stick properties that may not work with the metal plate.

    GMC base

    This is great. Mounts easy and very sturdy.

    Awesome Phone/GoPro mount

    Great product, this is my second unit. First one was in my Jeep gladiator and most recent is in my GMC AT4. Easy installation and places the device in a position I can easily record video while driving if I want.

    Sturdy and well built

    The mounting system is sturdy and well built. Would have given five stars but did not realize I had to drill into the dash for a secure fit. The double sided adhesive tape that is supplied for alternate mounting doesn’t stick to the factory tray.
